To. all whom it may concern;

Be it known that I, Ronnn'r E. Boomu, a citizen of the United States, and a resident of New York, in the county of New York and State of New York, have invented certain new and useful Improvements: in Portable Temperature-Regulating Ventilators, of which the following is a full, clear, and exact. description, w ereby any one skilled in the art may make and use the same.

The. invention, as indicated, by its title, relates to. a portable device which may be applied to or removed from a window, transom or other 0 ening) and relates more articularly. to a evice y which pure air rom I the'extei'ior. of the building may be passed into said building at varyin temperatures and without un' 'leasant cold drafts.

, The object o .the invention is to. provide a device of the character defined which may be formed as a' complete structure and may be inserted or removed from a window, transom or other opening.

A further object is to provide a temperature regulating ventilator which may be adjusted automatically or otherwise-to produce the fiow of certain volumes of ure air at predetermined temperatures to t e 1nter1or o'afTtli .room.

Referring to the drawings: Figure 1 is an inside elevation of a window-casing with the portable temperature re lating ventilator in place, parts being roken away in section to better illustrate the construction.

Fig. 2 is a cross-sectional view through the window-casing and ventilator a paratus illustrated in Fig. 1. Fi 3 is a lagrammatic view illustrating t e means for controlling the heating apparatus of the ventilator. Fig. 4 is a detalled view with arts broken away illustrating the method 0 controlling the louvers or shutters.

It has not been an unknown practice heretofo-re to use fans for inducing a flow of air in a window or like opening. It has not been an unknown ractice to usewhat has become commonly own as indirect radiation for securing the best heatin results, that is, positioning a radiator ad acent to a window and permitting the outside air to pass over said radiator and into the interior of the building. It has also been common practice to use portable ventilators, that 1s, devices which may be placed under the window sash and afford an indirect course to theoutside air which may enter the room throu h the ventilator. In the latter class of evices, if fully opened to secure the necessary-quantity of a1r within the building, considerable discomfort is experienced by the chilling of the air of the room at periods which necessitate the closin or shutting off'of the air suppl ere indirect radiation is used: an ob- JBCtlOIl is found in as much as in crowded rooms, not a suflicient quantity of heated air 1s forced into the room and where the heating lant or radiator is a fixed unit, great iscomfort is often experienced through over-heated rooms. This is due in a great measure to changes in temperature of the outside air, without a change in the condition of heat induced by the radiator. The result is that a sufiicient quantity of pure air is not sup lied to the room. In crowded rooms, suc as those employed in large cities where a number of operatives are engaged over confining work, it is impossible to use direct forced draft to secure pure air within the rooms. Itis also impracticable to use indirect radiation for the reasons above defined, and naturally, it is highly essential that the room be filled with ure moderately warm air to dis 1 the unygienic conditions of the vitiated air caused by the presence of carbonic acid gas which is the result of the exhaustion of the air by the lungs of the operatives.

It has been fairly well proven that the presence of a sufilcient quantity of fresh clear air reduces the tendency toward tubercul'ar troubles and other diseases so prevalent among those compelled to use crowded rooms and apartments, and it is one of the principal objects of the present invention to provide a compact and portable device which may be applied to a window, transom, or other openlng of a room, and which will give a maximum quantity of fresh air at'temperatures so regulated that I denotes. a window-casin of ordinary construction, provided wit the usual lower sash 2, and-Eupper sash 3, and having a s111 4, and outer ledge 5. The portable ventilatin apparatus is designed to rest upon the sil and ledge and be closel confined by the lower sash 2, as illustrate in Fig. 2.

The whole structure is self-contained and may be removed from or inserted within the window-openingat will, and may be formed of any desired material, either metal, wood, a transparent material such as glass or of several materials combined. It consists in the main of a base-piece or bottom 6, adapted to rest on the sill 4, and with a dependent portion 7, forming a support on the outer ledge 55.

An upper section 8, forms a rest against which the window sash may rest and this section 8, projects outside of the windowopening as at 9, to form a storm dri to carry away moisture which might fin its way down the window pane. The upper section 8, and lower baseiece 6, are closed at the ends and rising om the interior of the device is a shield or deflector 10, so arranged that a space 11, is provided between the top section 8, and said deflector. When the several parts are assembled, the upper section 8, base section and deflector form an inclosing box open to the outside air through an open side 12, and to the interior of the room, through the opening 11.

Adjacent to the outer opening 12, are a series of shutters or louvers 13, which are preferably pivoted to the ends of the box and controlled by a rod 14, to which they are secured through pivotal connections which rod may be moved by an operating handle 15. With this arrangement, the shutters may be opened to a greater'orlesser degree dependent upon the conditions of ventilation desired. Mounted within the box-like structure is a radiating device or heater 16, which may be of any desired type, although shown for convenience here, as a heater of the electric type. Between the louvers 13, and the heater 16, may be arranged a series of fans 17, in order to give a forced draft to the air passing over the heating device. When fans are used, it is desirable to use a translucent or other plate 18, perforated to receive the fan-blades in order to give a direct driving action to the air taken in from the outside and forced over the heater.

When an electric heater and electric fan are used, the temperature of the heater may be controlled by any of the well known types of thermostats which are not described spe v cifically herein and the heat radiated by the heater may be varied to maintain a 'constant temperature within the room without in any way interfering with the quantity of fresh air which is forced over the heater and modified as to tem erature. In Fig. 3, there is illustrated in iagram such an arrangement in which the circuit wires 19, 20, are connected through leads 21, 22, with the fan circuit which is controlled by a switch 23. I

The heating circuit is taken off on leads 24, 25, and a rheostat 26, in series with the line 24, and heater 16, is controlled b a thermostat 27, which may be arrange to automatically vary the quantity of current passed to the heater 16, dependent upon the temperature of the room. Of course, it is understood that the heating device, whether -it be electrical or of some other form, may

be similarly controlled by a thermostat and may be so arranged that the temperature of the air may have a lmown value as it is passed into the room.

The operation of the device is apparent. Referring to Fig. 2, the louvers 13, may be adjusted at will to determine the inlet opening. With the fans in operation, the air drawn in through the louvers and forced over the heater will, through the form of the inner wall 10, be driven about the casing and across the heater and will finally be deflected through the inner opening 11. Thus, a great volume of air may be forced into the room at a moderate and comfortable temperature. Should the atmospheric condition of the outside air suddenly change, the thermostat will vary the heat conditions of the heater 16, and the air passing thereover will thus be modified as to its tem erature. Thus. a constant temperature with a maximum quantity of pure fresh air may be maintained within the room to which the apparatus is applied. It will be observed that the base section of the casing is flat and adapted to rest upon the window sill and that it constitutes a substantially horizontal flat broad support of ample dimensions for the heater, or for both the heater and the fans when these are used together.

' Obviously, the exact details of the device might be varied to a considerable extent without departing from the spirit and intent of the invention and it is quite imma= terial what substances are used in the matter of construction. It is also immaterial what form of heater is used as the main conditions required may be attained in various manners.

What I claim as my invention and desire to secure by Letters Patent is A portable self-contained temperatureregulating ventilator comprising a boxlike casing adapted to be inserted in or removed from a vwindow opening and having an external opening to the outside atmosphere and an inside opening Within the apartment, forcing air over the heating device, and the a perforated plate dividing the casing arcurrent supply connections tor the heating ranged between the sald openlngs, an elecdevice and the fan.
